The Supplemantary design, motivated by [44], can be used to extend a previously generated Orthogonal Main Effect design. The design consist of the already analyzed Orthogonal Main Effect design were the additional parameters has normally its nominal value, and of a second Orthogonal Main Effect design were the value of the additional parameters is set to its minimum or maximum value.
Table 3.8 lists the sample points for an Supplemantary design from the Orthogonal Main Effect design shown in Table 3.7.
